I just reset a 04 Toyota RAV 4 with the same method as I saw used on a Honda.
1) Press and hold in the trip/odometer stick where the mileage is displayed (near speedometer).
2) Turn the key and wait for about 5 seconds... light goes out (as long as nothing else is wrong I assume)
3) Don't forget to change oil!!!

The reset switch for the fuel pump on a Toyota Echo depends on the year it was made. It is either in the trunk, under the carpet, or it is under the passenger side dash.
You can either fix whatever problem is causing it, or have it reset with a code reader. If you reset it with a code reader, chances are it will come back on.
You discount the negative cable from the battery and press the brake pedal for at least ten seconds.
